NetGuard — Vulnerability Scanner & Hardening

System Hardening

Server and network hardening based on CIS Benchmarks

Audit every server, operating system and network device against secure baselines, catch configuration drift and close the gaps attackers rely on.

What is system hardening?

System hardening means configuring operating systems, applications and network devices to minimize their attack surface: disabling unnecessary services, enforcing strong authentication, restricting permissions, enabling logging and applying secure defaults.

Most breaches don't need a zero-day — they exploit weak configuration. NetGuard turns hardening from a one-time project into a continuous, measurable process by auditing systems against CIS Benchmarks and your own security baselines.

What NetGuard hardening covers

Windows & Linux servers

Password and account policies, services, file permissions, audit logging and more.

Network devices

Routers, switches and firewalls checked for insecure management access and weak settings.

Databases & web servers

Secure configuration of common database engines and web servers.

Custom baselines

Build your own policies on top of CIS Benchmarks to match internal standards and regulations.

How hardening works with NetGuard

  1. 1

    Choose a baseline

    Start from CIS Benchmark profiles or your organization's hardening standard.

  2. 2

    Audit configurations

    Credentialed checks compare every setting on every system against the baseline.

  3. 3

    Remediate

    Each failed control comes with its rationale and exact remediation steps.

  4. 4

    Prevent drift

    Continuous audits alert you when a hardened system drifts from its baseline.

FAQ

Frequently asked questions

What is system hardening?

System hardening is the process of reducing a system's attack surface by removing unnecessary services, closing unused ports, enforcing strong authentication and applying secure configuration settings. Hardening is usually measured against a baseline such as the CIS Benchmarks.

Which standards does NetGuard support?

Findings are mapped to CVE, CVSS and OWASP Top 10, and hardening audits follow CIS Benchmarks. Reports can be mapped to ISO/IEC 27001, PCI DSS and NIST controls.

Can NetGuard be deployed on-premises?

Yes. NetGuard can run entirely inside your data center, including isolated and air-gapped networks, so scan data never leaves your infrastructure. A private-cloud option is also available.

Will scanning affect my production systems?

NetGuard uses safe checks by default, with bandwidth limits, concurrency controls and scan windows, so you can assess production environments without disrupting them.
